d100 Mental Mutations

Mental powers are some of the most exotic mutations and have a increased chance of mental defects or powers that will cause problems. Most powers have visible effects when in use. Mental powers might be known as psionics or psychic powers or spell like abilities are used for such powers.  Names used for practitioners include mesmerist, medium, mystic or even witches.

Powers not divided into types like most mutations based on organs or body parts. Possibly more powerful than other tables but some more detrimental. Some of the major mutations are problems too. Some of these risk your characters personality and behaviour while previous ones are mostly cosmetic. Psionic mutants probably blend in better but might go crazy or look scary using powers. Many petty powers are in fact brain defects or mental illnesses. Some of the later major powers might seem liabilities - serenity, pacifism, berserker.

I do also have a Psionics spell system that has proven popular in my games replacing standard psionics and illusionists. I let ppl take this list for clerics or elves or bards or wizards if they want to be from a alternate tradition.

Psionics Spell list and Classes
Psionics and Sorcery Mentalist Spell List 1-3
Psionics and Sorcery Mentalist Spell List 4-5 with Shaman Class
Psionics and Sorcery Mentalist Spell List 6-7 with Psionicist Class

Trained psionics tend to look down on mental mutants.

This is probably my final word in mental powers and psionics for my games. I've always hated creating whole crazy new systems for powers and felt most oficial systems broken.
